One overriding theme I've noticed in learning Japanese and consuming the media of the country is how vastly different the vocabulary and way someone speaks is between people affecting different levels of politeness in different contexts. My main question is what should the base level of vocabulary a student should get down before moving on to the others, or does that rely on the intent of the student?
The less important questions I have revolves around the use of Japanese in fighting games. Aside from learning the regular vocab, what specific terms should I know if I want to better understand it(example:http://www.youtube.com/watch?v=trwyy_RnFfM&feature=related)? One term I seem sounds something like 'seki ari' and translates to opening, but nothing I've pored over states that meaning with those words. What would the term for an opening be, in terms of facing someone in combat?
